Metal halide perovskites (MHPs) have been shown to be key materials for next-generation photovoltaic energy harvesting, electro-optic detection, and all-optical conversion. Room-temperature tetragonal MAPbI₃ has been reported to possess two space groups: polar I4cm and non-polar I4/mcm. Although the space group of MAPbI₃ is still under debate, significant effort has been expended to prove that I4cm MHPs are ferroelectric and I4/mcm MHPs are antiferroelectric. Both structures belong to the ferroelastic point group, and there has been debate regarding whether the domain structures observed on MHPs are ferroelectric or ferroelastic. The relationship between the ferroelectricity and ferroelasticity of MHPs has been discussed, whereas these two properties sometimes are regarded as mutually exclusive in MHPs. In this work, the ferroelectricity and ferroelasticity of MHPs originating from structural symmetry have been reviewed, and the interrelationship between the ferroelectricity and ferroelasticity of MHPs are discussed.

应变钙钛矿薄膜中的铁弹性介导的能量转换

金属卤化物钙钛矿（MHP）已被证明是下一代光伏能量收集、电光检测和全光转换的关键材料。据报道，室温四方MAPbI ₃具有两个空间群：极性I4cm 和非极性I4/mcm。_{虽然 MAPbI 3}的空间群仍在争论中，已经付出了巨大的努力来证明 I4cm MHP 是铁电的，而 I4/mcm MHP 是反铁电的。这两种结构都属于铁弹性点群，关于在 MHP 上观察到的畴结构是铁电还是铁弹性一直存在争议。已经讨论了 MHP 的铁电性和铁弹性之间的关系，而这两个特性有时在 MHP 中被认为是相互排斥的。在这项工作中，回顾了源自结构对称性的MHP的铁电性和铁弹性，并讨论了MHP的铁电性和铁弹性之间的相互关系。
